+# PlaceholderKit
+
+[![Build Status](https://travis-ci.com/simonlee2/PlaceholderKit.svg?branch=master)](https://travis-ci.com/simonlee2/PlaceholderKit) [![codecov](https://codecov.io/gh/simonlee2/PlaceholderKit/branch/master/graph/badge.svg)](https://codecov.io/gh/simonlee2/PlaceholderKit)
+
+
+## Features
+
+- Generate placeholder UIImages
+- Import images to cameral roll
+
+## Why do I need it?
+
+There's a lot more to calculating diffs than performing table view animations easily!
+
+Wherever you have code that propagates `added`/`removed`/`moved` callbacks from your model to your user interface, you should consider using a library that can calculate differences. Animating small batches of changes is usually going to be faster and provide a more responsive experience than reloading all of your data.
+
+Calculating and acting on differences should also aid you in making a clear separation between data and user interface, and hopefully provide a more declarative approach: your model performs state transition, then your UI code performs appropriate actions based on the calculated differences to that state.
+
+## How to use
